SNAP=HOOK.

SPECIFICATION forming part of Letters Patent No. 397,948, dated February 19, 1889.

Application filed May 23, 1888. Serial No. 274,789. (No model.)

To all whom it may concern:

Be it known that I, ROBERT R. WADDELL, a citizen of the United States, residing at Hillsborough, in the county of Highland and State of Ohio, have invented a certain new and useful Improvement in Snap-Hooks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth ers skilled in the artvto which it appertains to make and use the same.

The object of my invention is to provide a securing device or hook for use in connection with bridles, reins, and all kinds of harness, and which may be used for the suspension of various articles and whenever such a device is desirable.

In the accompanying drawings, Figure l is a side elevation of my device. Fig. 2 is a side elevation with a portion of one of the arms removed in order to show a guideway on the spring-cylinder. Fig. 3 is a longitudinal sectional view taken on the line m Fig. 4

is a diagram showing the opposite pointinghooks.

In the drawings, A A indicate two arms, made, by preference, of some light malleable metal. These arms are made yoke-shaped,

and may be either of one continuous piece, j as shown, or they may be made separate and united at the top by a cross-bar. The lower extremities, a. (l, of the arms are curved upwardly in hook shape, the hooks being pretl and a pin extending inwardly from one of erably turned in opposite directions.

B is a hollow cylinder, which may be open at both ends and provided with internallyi projecting pins, or one end may be closed and the other provided with a pin, as D. In the hollow portion of the cylinder is a spring, C, which is secured to the projecting pin D. This cylinder may be made of any suitable material. Both sides of the cylinder are provided with grooves h b, in order that it may be guided by the arms in its lengthwise movements. One of the guide-grooves is slotted in order to receive the inwardly-projecting pin D, which is secured to one of the arms A. In the hollow portion of the cylinder, and attached to that part of the pin D which projects into the cylinder, is attached a spiral spring, E. At the lower portion of the cylinder B the grooves are enlarged, as at F, in order to admit of the curved portion of the arms A where they begin their enlargement into hook shape. The cylinder B normally rests with one end in contact with the outer ends of the hooks a ct, being held in that position by the spiral spring, one end of which spring, as already stated, is attached and prevented from moving past the pin D.

In order to indicate the use of my device, I have shown a ring, G, as engaged by the hooks a a.

The cylinder B acts to retain in the hooks the article thereto attached.

The operation of my device is as follows: In order to insert the ring or part to be attached to the hooks a a, the cylinder B is moved lengthwise against the tension of the spring E by inserting the ring or other article between the hooks a a and pressing the cylinder B upward against the tension of the spring E, and then on giving a quarter-turn to the ring or other device to be secured and releasing it the spring-cylinder forces it (the ring) into engagement with hooks a a..

I claim as follows:

l. A snap-hook comprising a wire yoke, the lower ends of which are reversely turned, forming hooks, a hollow side grooved cylinder iitted between the yoke-arms, a spring iitted in said hollow portion of the cylinder,
